On Hainan Island, 24 species of Gesneriaceae are naturally distributed, among which eight are endemic. Ling et al (pages 847–815) studied the distribution patterns and phylogenetic relationships of Gesneriaceae in Hainan Island: (for details see. The pictures show the eight Hainan-endemic species. From the upper to bottom, they are Metapetrocosmea peltata, Paraboea changjiangensis, and Oreocharis dasyantha in the left column; Chirita heterotricha and Paraboea hainanensis in the middle column; Oreocharis flavida, O. dasyantha var. ferruginose, and Cathayanthe biflora in the right column.
